Abstract
The utility model relates to an ultra-thin type magnetic machinery sealing structure which is characterized in that an iron ring friction surface (7) is arranged on an end cover static ring (1); a movable ring friction surface (8), a magnetic ball mounting hole (3) and a frame seal (5) are arranged on a movable ring (2); an ultra-intense magnetic ball (4) is mounted in the magnetic ball mounting hole (3); the ultra-intense magnetic ball (4) is attracted with the iron ring friction surface (7) of the end cover static ring (1) , attracted and contacted with the movable ring friction surface (8) of the movable ring (2) so that the double end surfaces non-leakage seal is realized; a positioning O-shaped ring (6) is mounted on the inner ring of the frame seal (5); the inner ring of the frame seal (5) is tightly fixed on the pump shaft by the positioning O-shaped ring (6) to realize the automatic positioning seal. The ultra-thin type magnetic machinery sealing structure can be widely applicable to the fields of various pumps, kettles, reducers, gearboxes, ventilators and blowers.
Description
Technical field
The utility model relates to the mechanical sealing technology field, is specifically related to a kind of ultrathin magnetic mechanical seal structure.
Background technique
Sealing is a pump class most key part; it is directly connected to the working life of pump class; adopt patterns such as packing seal, reinforced seal, spring mechanical sealing for many years always; directly wear and tear pump shaft, wasteful, life-span of packing seal and reinforced seal is short; though mechanical seal has overcome above-mentioned defective; take up room greatly but still have, can't be used for vertical pump, in start, cause leakage easily when shutting down, cost an arm and a leg, defective such as inconvenient maintenance.
Summary of the invention
For overcoming above-mentioned technological deficiency, the utility model provides that a kind of volume is little, the life-span is long, price is low, leak free ultrathin magnetic mechanical seal structure.
For achieving the above object, the utility model adopts following technical proposal:
A kind of ultrathin magnetic mechanical seal structure, form by end cap stationary ring 1, rotating ring 2, magnetic bead mounting hole 3, superpower magnetic bead 4, reinforced seal 5, location O type circle 6, iron hoop rubbing surface 7 is set on end cap stationary ring 1, rotating ring rubbing surface 8, magnetic bead mounting hole 3, reinforced seal 5 are set on rotating ring 2; The magnetic force of adorning superpower magnetic bead 4, superpower magnetic bead 4 in the magnetic bead mounting hole 3 directly with iron hoop rubbing surface 7 adhesives of end cap stationary ring 1, and contact with the rotating ring rubbing surface 8 mutual adhesives of rotating ring 2, the realization Double End does not have leakage and seals; Its reinforced seal 5 inner rings are equipped with location O type circle 6, and location O type circle 6 is fastened on reinforced seal 5 inner rings and forms self-align sealing on the pump shaft.
Described iron hoop rubbing surface 7 and end cap stationary ring 1 are the integral piece of identical material or the disjunctor assembly parts of unlike material.
Described magnetic bead mounting hole 3 is two types, and A is poroid, and B is the circular groove shape.
Described superpower magnetic bead 4 is made up of magnetic bead and magnet ring.
By adopting technique scheme, thoroughly solved spring type mechanical sealing at start, the leakage problem that causes when shutting down, and make that it is simple in structure, volume-diminished, cost reduce, installation and maintenance are convenient especially, and have increased the working life of pump greatly.
Description of drawings
Fig. 1 is the ultrathin magnetic mechanical seal structural representation of the utility model.
Among the figure: 1 end cap stationary ring, 2 rotating rings, 3 magnetic bead mounting holes, 4 superpower magnetic beads, 5 reinforced seals, 6 location O type circles, 7 iron hoop rubbing surfaces, 8 rotating ring rubbing surfaces.
Embodiment
The utility model as shown in Figure 1; The iron hoop rubbing surface 7 and rotating ring 2 integral body of end cap stationary ring 1 are pulled together, by location O type circle 6 reinforced seal 5 is fixed on the pump shaft, and by reinforced seal 5 location, make the rotating ring rubbing surface 8 formation Double End rotary seals of iron hoop rubbing surface 7 with the rotating ring 2 of end cap stationary ring 1, realized whole nothing leakage sealing; The utility model only need take off location O type circle 6 when installing and changing this sealing, rotating ring 2 integral body are put into, and loads onto location O type circle 6 then and gets final product.
The utility model is simple in structure, cheap, installation and maintenance are convenient especially, can be widely used in fields such as all kinds of pumps, still, speed reducer, ventilator, blower.
